Burst switching

Burst switching: In a packet-switched network[?], a switching capability in which each network switch extracts routing instructions from an incoming packet header[?] to establish and maintain the appropriate switch connection for the duration of the packet, following which the connection is automatically released.

Note: In concept, burst[?] switching is similar to connectionless mode transmission, but it differs from the latter in that burst switching implies an intent to establish the switch connection in near real time so that only minimum buffering is required at the node switch.
